Hello. I can't seem to get the module class suffix to work in this module. When the suffix is added, it distorts the module. I bought this two years ago and I'm trying to style the various module positions. I don't know what I am doing wrong.

I am trying to add custom styling to my site http://tinyurl.com/ne64os6

1. I enter a class name in the module class suffix in the module I'm trying to style. In this case, it is the module Things To Do in the Side COl B position. I called the suffix greenClass.

<div class="module_greenClass"> which expands to <div class="module">

When I click <div class="module">, I see the code in the right pane which I have copied below.

.sidecol_block .module {
color: #ffffff;
}
.sidecol_block .module, .sidecol_block .module_menu {
margin-bottom: 20px;
}
.sidecol_block .module {
background: rgba(0, 0, 0, 0.35) none repeat scroll 0 0;
border-radius: 5px;
box-shadow: 0 0 0 1px rgba(0, 0, 0, 0.2) inset, 0 1px 0 0 rgba(255, 255, 255, 0.1);
}

If I adjust the background rgb value, both modules in the SIde COl B position change color. What am I to do to get only the "Things To Do" module to change?
